The present disclosure generally relates to a retaining apparatus, and more specifically, to an apparatus for retaining an aerosol container within a dispenser housing to emit materials into the surrounding environment.
Fluid dispensers are common devices used for the emission of volatile materials into the surrounding environment, such as the release of a pest control agent or the release of a pleasant aroma or odor absorbing agent. Dispensers configured to accept refill containers are an economical way for consumers to re-use a dispenser without having to re-purchase a device. Further, refills afford the user the possibility to change the properties of the fluid that are emitted.
One of the challenges faced by some manufacturers of dispensers and dispenser refills is preventing the use of unapproved or improper refills in the dispensers, e.g., preventing the dispensing of an external use insecticide into an interior environment or dispensing an air freshener when an odor absorber was desired. In many instances the improper spraying of such materials may result in a user being dissatisfied with their experience or the malfunction, destruction, or reduced operability of the dispenser because of the use of an improper material.
Therefore, there is a need for a retaining apparatus that overcomes one or more of the aforementioned drawbacks of dispenser refills. In particular, there is a need for a retaining apparatus that retains and positions an appropriate container for use in a designated dispenser and that prevents the misuse of the container in other applications.
According to one aspect, a retaining apparatus is configured to couple to a valve stem of an aerosol container and to interface with a dispenser to actuate the valve stem. The apparatus includes a body portion having an internal bore configured to receive a valve stem. The internal bore has an internal diameter. A wall has a thickness defined between the internal bore and an exterior surface of the body portion. The body portion further includes an aperture having a diameter selected to avoid atomization of fluid travelling through the aperture. The wall thickness is selected to prevent collapsing of the wall when the valve stem is actuated.
According to another aspect, a retaining apparatus is configured to couple to a valve stem of an aerosol container and to interface with a dispenser to actuate the valve stem. The apparatus includes a body portion having an internal bore configured to receive a valve stem. The internal bore has an internal diameter and length. The body portion further includes an aperture having a diameter selected to avoid atomization of fluid travelling through the aperture. The valve stem extends at least about 1.7 mm into the internal bore.
According to a further aspect, a retaining apparatus is configured to couple to a valve stem of an aerosol container and to interface with a dispenser to actuate the valve stem. The apparatus includes a body portion defined between an exterior surface and an internal bore configured to receive a valve stem. The body portion further comprises an upper surface and a frustoconical surface or a shoulder between the upper surface and an exterior surface. The frustoconical surface or the shoulder is configured to interface with an angled or rounded surface on a dispenser in order to actuate a valve stem.
Other aspects and advantages of the present invention will become apparent upon consideration of the following detailed description, wherein similar structures have similar reference numerals.
The proper securing of a container into an appropriate dispenser by way of a retention apparatus enhances the user's ability to safely operate a dispenser for emitting a material. For example, a retaining apparatus should preferably only be capable of fitting retention in an identified corresponding dispenser. In many instances the improper spraying of such materials may result in a user being dissatisfied with their experience or the malfunction, destruction, or reduced operability of the dispenser because of the use of an improper material.

The aerosol container 100 includes a reservoir or lower portion 102 and a sealing cap or upper portion 104. A lower rim 106 of the sealing cap 104 and an upper tapered portion 108 of the reservoir 102 define a retaining notch 110 that circumscribes the aerosol container 100. A valve stem 112 extends vertically from an upper portion 114 of the sealing cap 104. It is contemplated that in some embodiments that the valve stem 112 may be a vertically actuated valve stem. In other embodiments, the valve stem 112 may be a tilt-actuated valve stem.
The container 100 holds and/or stores a fluid product such as a fragrance, an insecticide, a deodorizer, a fungicide, a bactericide, a sanitizer, a pet barrier, another active volatile or other compound disposed within a carrier liquid (for example, an oil-based and/or water-based carrier), a deodorizing liquid, or the like. For example, the liquid may comprise PLEDGE®, a surface cleaning active, RAID®, a pest control active, OUST®, an air and carpet sanitizer, or GLADE®, a deodorant, all sold by S. C. Johnson and Son, Inc., of Racine, Wis., for household, commercial, or institutional use. The liquid may also comprise other actives, such as sanitizers, air and/or fabric fresheners, cleaners, odor eliminators, mold or mildew inhibitors, insect repellents, and the like, or others that have aromatherapeutic properties. The liquid alternatively comprises any fluid known to those skilled in the art that can be dispensed from the container 100. The container 100 may employ a propellant such as, for example, compressed gas, liquefied petroleum gas (LPG), and/or one or more additional and/or alternative propellants to facilitate dispensing of the fluid product from the container 100.
The dispensers described herein may be used as stand-alone devices, which may be placed on a table, shelf, or other flat surface. Alternatively, the dispensers may be utilized as hand-held devices. The dispensers may be used in an interior room or office and/or outside on a table or other surface. With reference to

While the embodiment depicted in
It is contemplated that one or more aspects of the upper portion 230 of the retaining apparatus 216 overcomes the drawbacks to refill containers described above. First, the upward facing teeth 232 can serve multiple purposes. The length of the central tube 234 to the teeth 232 may provide a structural relationship such that a seal is impossible to form between the central tube 234 and an improper dispenser. Further, the appearance in general of the upward facing teeth 232 and the retaining apparatus 216 may serve as a visual indicator to a user about the purpose of the refill. Also, the enlarged diameter of the central tube 234 of the retaining apparatus 216 in comparison to a diameter of the valve stem 112 of the container 100 may also prevent different containers from establishing fluid communication with unintended dispensers. As configured in the present embodiment, any dispenser that receives the retaining apparatus 216 will need a receptacle that is configured to receive the central tube 234, which has a larger diameter than the valve stem 112.

A plurality of upward facing teeth 360 are disposed on the top wall 344 and are coupled to or integrally formed with the central tube 346. In certain embodiments there may only be a single upward facing tooth 360 and the corresponding discharge portion 240 of the base 202 would be configured to receive it.
Another embodiment of the retaining apparatus 300 is depicted in
Regardless of the embodiment, it is contemplated that the actuation of the valve stem 112 of the container 100 is similar to the interaction of the retaining apparatus 216 with the discharge portion 240. Instead of the resilient arms 252 deforming, the upper portion 330 is displaced downward into the bridge portion 332 to allow for actuation of the valve stem 112. It is also contemplated that the retaining apparatus 300 may retain the container 100 in the same configurations as the retaining apparatus 216 within the dispenser 200.

With reference still to
The inside diameter ID is contemplated to be about 1.4 millimeters (mm). In one embodiment the inside diameter ID is between about 1.1 mm and about 1.7 mm. In a different embodiment the inside diameter ID is between about 0.8 mm and about 2.0 mm. It is also contemplated that the outside diameter OD be about 4.6 mm. In some embodiments the outside diameter OD is between about 4.4 mm and about 4.8 mm. In other embodiments the outside diameter OD is between about 4.2 mm and about 5.0 mm. In one particular embodiment, the inside diameter ID and the outside diameter OD are at least about 0.8 mm and 4.2 mm, respectively. As mentioned above, the wall thickness WT of the central tube 504 is defined as half of the difference between the outside diameter OD and the inside diameter ID. In some embodiments the wall thickness WT is about 1.6 mm. In other embodiments, the wall thickness WT is between about 1.45 mm and about 1.75 mm. In still other embodiments, the wall thickness is at least about 1.45 mm. It is contemplated that the wall thickness WT impacts the ability of the retaining apparatus 500 to survive the insertion process of the valve stem 112 and the insertion of the central tube 504 in the central dispensing bore 246 of the dispenser 200. In fact, insufficient wall thickness WT may result in cracks or failure that prevent the appropriate seals to be formed.
It is also contemplated that the upper tapered portion 514 has a discharge aperture 520 with an aperture diameter AD (see
